There are 3 ball mills in our plant so we should differentiate between ball mill power and total power of ball mills which is sum of each ball mills power. By increasing throughput the mill power will increase too but it will also let us to send one of ball mills as a standby so total power seems to remain unchanged.

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

One way of fully utilising the capacity of a ball mill is to convert it from an overflow to a grate discharge. This can allow an operation to increase plant throughput or reduce the product size, which can each contribute to higher revenue, but there are several factors to consider before the decision to convert is made.
